About the battery care function of SONY notebook and the charging of the battery

The battery is active at the factory, but it is recommended to perform three full charges and discharges to make the battery in the best possible condition. Regardless of the remaining battery and whether it is fully charged or not, as long as there is a charging and discharging process, the life of the battery will be reduced once. If the battery is not used often, it is recommended that when the battery is about half used, take it off the computer and store it separately.

When you use half of the remaining power, it is best to store it for a long time, and the storage temperature is best at 0-10 degrees, the higher the temperature, the greater the battery damage. The most taboo is to store the battery after it has been completely discharged. If conditions permit, complete charging and discharging should be done once a month or so.

Whether it is a laptop battery or a mobile phone lithium battery, the manufacturer will never leave the factory with a full charge.

For laptop batteries, you don't have to use them all up and then charge them, when you have been using the computer, you can take the battery and plug it directly into the power supply, so that your battery can be wrapped.

Here, the charging threshold should not be set too low!

It is recommended that you increase the charging threshold (not lower the better).

How to fix laptop battery.

Hope it helps!

It is possible that the battery itself is a hardware failure. Generally speaking, you can tell by restarting your computer and replugging the battery, but if the battery still won't charge, you might want to install some hardware detection app to see if the battery is wearing too much.

Introduction: Laptops are also known as:"Laptop, laptop, PDA or laptop"Its biggest feature is that the body is small, which is easy to carry compared to a PC, and is a small, portable personal computer, usually weighing 1-3 kg.

Hard drives: The performance of hard drives has a critical impact on the overall performance of the system. The hard disk used in laptops is generally inches, while desktops are inches, laptop hard drives are one of the few universal parts in laptops, basically all laptop hard drives can be universal.

Hard disks can also be divided into mechanical hard disks and SSD solid state drives. Mechanical hard disk is the ordinary hard disk we are familiar with, and its structure is composed of: platter, magnetic head, platter rotating shaft, control motor, magnetic head controller, data converter, interface, cache and other parts.

Expand: Unlike desktop computers, the battery is not only one of the most important components of a laptop, but also largely determines how easy it is to use. For laptops, the requirements for light and thin make the battery requirements extraordinary.

According to IDC's research report, compared to factors such as weight, display size, and backlight, the battery life of laptops is the most important concern for users.

1.Read the battery care section of the user manual carefully before using the laptop;

2.On the first charge, you should charge the battery continuously for 12 hours, and fully charge and discharge 3 times in cycles to fully wake up the new battery;

3.If you use an external power supply for a long time, it is best to remove the battery. Many friends have not noticed this problem, not removing the battery when using an external power supply not only affects the life of the pool, but also makes the heat dissipation burden of the laptop heavier and shortens the life of the laptop;

4.Charge and discharge regularly. Even if lithium-ion batteries without memory effects have a certain inert effect, they will be inactive if they are not used for a long time and need to be reactivated.

Therefore, if you do not use the computer for a long time (3 weeks or more) or find that the battery charge and discharge time becomes shorter, you should make the battery fully discharged and then recharge, generally at least once a month.

5.It's best to turn off the laptop while charging so that the battery can be fully charged, and don't unplug it in the middle of charging. Charging when powered off will reduce the charging time by more than 30% compared with charging when it is turned on, and it can extend the service life of the battery.

It is best to use it 30 minutes after charging.

6.Prevent exposure to sunlight, moisture, chemical liquids, and short circuits in contact with metal objects. The number of charging times of lithium batteries is generally not more than 800 times, and each time it is charged, it shortens the life of one time.

It is recommended that you try to use an external power supply, if you need to plug and unplug the power supply many times during use, and the built-in battery of the laptop is not unplugged, it will make the battery lose a lot of life, because each time the external power supply is connected, it is equivalent to charging the battery once.

The battery life should remain at about 2 hours (Vista system) and the power consumption is high on the discrete graphics configuration. Usually, don't unplug the power supply and connect it again many times, the performance of the battery repeated charging has a great impact.

Sony Laptop Battery Repair Method:

1. If you use the external power supply for a long time, it is best to remove the battery, which can prolong the service life of the battery. Reason: Due to the different brands, models, and ** of notebook computers, their power circuit design is also different.

A good notebook circuit design is more scientific, when using an external power supply, it will disconnect the battery and be powered by the external power supply alone, and when the external power supply is unplugged, it can quickly switch to battery power supply. When the battery is fully charged, it can be automatically disconnected and no longer charged. If this is the case, there is no need to remove the battery.

But not all notebooks are designed like this! Some laptops still drain the battery when using an external power source; There are also notebooks that don't automatically stop charging when the battery is fully charged. If this is the case, the battery must be removed.

Although it will be beneficial to remove the battery when using the external power supply for a long time, the frequency should not be too high, otherwise the interface of the battery will be worn; Loosening occurs. When the laptop is turned off and the external power supply is unplugged, it is best to install the battery, otherwise it is not very reliable to rely on the coin cell battery on the motherboard to power the CMOS chip for a long time.

2. Laptop batteries should be calibrated every once in a while (about one year). The principle of laptop battery correction is not to activate the battery (lithium-ion batteries do not need to be activated), but to allow the laptop to reconfirm the battery level.

3. If the laptop battery is not used for a long time, the following operations need to be carried out: first fully charge the battery, then use half of the power, and then save it. Don't take too long, repeat the above operations within half a year.

4. The service life of the lithium battery is calculated by the number of full charges, so you don't have to wait for the battery to run out of power, and it does not affect the service life. For example, charging halfway through use is not a complete charge but a full charge.

5. Lithium batteries have no memory, there is no need to discharge, and there is no need to wait until they are used up to recharge, and the rapid power loss mode will consume a large number of lithium ions, so that the battery capacity is reduced. In fact, when lithium batteries are used in various electrical appliances, although the power is exhausted, there is actually a part of the remaining power, which is the protection measure of lithium batteries. Because once the lithium battery is completely depleted, it will no longer be able to be used because it cannot be charged!

Therefore, lithium batteries should not be left unused for a long time when the power is very low, otherwise the battery will be scrapped directly!

6. Lithium batteries are different from nickel-cadmium and nickel-metal hydride batteries, and they do not need to be activated at all! Many people's minds are also influenced by nickel-cadmium and nickel-metal hydride batteries, thinking that as long as it is a rechargeable battery, it needs to be activated, which is completely wrong! The so-called activation (long charging) only shortens the life of the lithium battery.

Because the AC clutter used in China will have an impact on the life of the rechargeable battery, fast charging is better than slow charging. In short, try to keep the charging time as short as possible.

There are two possibilities, one is the battery itself, and the chip inside is broken; The second is a system problem, which may be a mistake in the computer's system in terms of power management. You said that your battery can be discharged for 4 hours, it shouldn't be a problem with the battery, maybe it's a system error. If Master Lu can display battery information (not power), then the battery will be fine.

Under re-maintenance, lithium batteries generally have a two-year lifespan!

1. They are all lithium batteries, and it doesn't matter how much power is left to charge, it doesn't affect the battery life. However, it is better to remove the battery when you do not want it, and be careful not to run out of power.

2. Power supply.

3. It doesn't matter how much. Let me ask you, when you need to use it, do you not use it because there is only 50% of the battery left?

4. Use it every day, and after 3 years, the battery power will drop to about 50% 70% of the original, and personal experience ......

The life span of a computer is only 3 to 5 years, and it must be extremely slow after a long time, and no matter how good the maintenance is, it is the same. Therefore, it is a ...... to save if you can save it, use it when you need it, and spend money

How to extend the use time of the notebook as much as possible when using it?

1.The screen brightness is turned down. The LCD screen is a large power consumer, and the reduction of brightness can effectively prolong the use time;

2.Turn on power-saving features like Speedstep and PowerPlay. Today's notebook processors and display chips have the function of reducing the operating frequency and voltage to extend the use time, and turning on the corresponding options can greatly extend the battery life;

3.Spin down software using hard disks and optical drives. Software such as Nero DriveSpeed and PowerBooster can reduce the speed of optical drives, hard disks and other drives, and can also effectively reduce the power consumption of notebooks.

4.Make good use of standby, hibernation, and other functions. When the computer is not used for a long time, the laptop can be left on standby or hibernated, which not only saves power but also prolongs the life of the computer.

The debate about batteries continues, and if readers have any objections, they can discuss it on my blog, so let's work together on this controversial topic.

You can click on the main menu, which has instructions for using viao, and you have a detailed introduction.

2. In the future, only connect the battery when it is necessary to use it, and try to remove it at other times and seal it in a plastic bag for preservation. If the battery is not used for a long time, it should be charged once every six months.

3. After the power is turned off and the power is off, the battery begins to discharge slowly, and it will be charged once when the power supply is connected. If you've been on your computer all the time, this charging must have happened multiple times. At present, the best batteries have about 1,000 recharges (lifespan), and most batteries only have a few hundred times.

Blocking some kind of battery like Sanyo, it will definitely be eye-catching that it can be charged thousands of times.

My laptop is a Sony S138EC B

First of all, you have to figure out the actual meaning of Sony's battery maintenance function, this function is to shield part of the capacity of the battery, which is used to replace the reduced capacity of the notebook battery after aging in the future, and is used to increase the number of battery charging and discharging. Generally, the number of charging and discharging of notebook batteries is 500 1000 times (generally 500 700 times), but there is another situation is the aging of the battery cell.

Those who know computers know that the "six-core battery" and "nine-core battery" of the notebook refer to the battery cell 18650 or 18500 lithium battery inside, and the six-core is the six-cell lithium battery. The second is that the light energy is charged and cannot store electricity, for example, the old notebook runs out of power when it is turned on with a battery. Sony's technology is an improvement on the second case, but it comes at a cost, as it can only be charged to 50% or 80% (there are two options) when used before, so this technology is designed for people who use laptops and don't often run on batteries.

In short, there are 3 options: 1. Without turning on the function, you can use the entire laptop battery; 2. Turn on the "battery maintenance function 80%", you can use 80% of the battery, if the battery life decreases in the future, the system will automatically replace the damaged battery with 20% capacity; 3. Turn on the "battery maintenance function 50%", you can use 50% of the total battery capacity, so that you can have twice the service life of the original battery design life. Weigh the pros and cons yourself, and choose to use it.

Look for the battery item in the Vaio Control Centre, and remove the power maintenance item. If you want to replace the original system, it will be gone.
